BALL-BEARING. 1

Application filed Aiigust 19, 1908. Serial m5. 449,338.

Be it known that I, OTTO VON- Soiai'rrz, a subject of the King of. Prussia, residin at ermany, have invented new. and use 111 Improvements in Ball-Bearings, of which the following is a specification.

Thismvention relates to ball-bearings comprising concentric racerings having rooves or race-ways in their confronting oesfor receiving one or more series of balls, provision being made for introducing the balls laterally into the ball-race estab-. lished by said race-ways. t

The object is to provide a filling passage which owing to a certain resiliency of the adjacent metal, is contracted but adapted to yield or expand to allow maybe produced in various ways, a pre- =-ferred means being incisures in the rings ,near the passa e, thus providing elastic lips. which are disp aced 7 tie passages permits of the insertion of. the 7 balls without resorting 11011118 elasticity of the whole rings of hardened steel,"as hithertoemployed. I

In the accompanying drawing, which forms a part of this specification, the invention is illustrated in connection with a ball ring having a single series of balls. Figurel represents a side elevation of a ballbea ring embodying the invention. Fig.

i i 4 throughout 2 is a vertical cross section illustrated in Fig. 1. Fig. 3 is a similar cross section of the bearing showing a modified arran er'nent of'the passage.

Like re the sevei'al figures of the draw-1 .m

of the confronting peripheries Ofsthesaid rings 9 and h, shoulders m on the sides, of the path o f-the ballsiand embracing-the latter prevent the race rings from axial dis-iv m into the racegroov'e and preferably liaye tached lips a overhanging and contractin the balls to. pass through; it being understood of course that the lateral interstice bet-ween the rings is of by the balls-as the latter shown in- Fig.1 13x0 avoid obscurity of repre r. are forced through. This provision-of elas-' of'the bearing erence letters denote like parts,

. the purpose of: contracting the "passage. x;,F urthern1ore, the described yieldin'gnessof 100 the passage cambeproduced with the entire ,dispensation with an'yincisure by altering Referring to Figs-,1 and 2, g is the outer face ring and'h is the inner race ringyof the. bearing the balls d of which are contained and work in hollow or channeled race ways,

v sage in'such a manner that the -:walls notches ayieldingly-i iveway findetthehflanges or shoulders m of one or bothrings,

which'notches extend across the 'ent ireflan an inclined bottom; the opening formed by these notches n, when located oppositeo another, being; smaller than thedianiet'e'r" the balls at. The saidjnotch es may, vs

tical or may assume any desired inclination with respect. to the rac 'e'ways. The required yieldingness of thepassage is'attain'ed by -means of incisures b, arc-shaped or other 'wise formed, which surround or intren'ch the notches, thereby producing semi de'-* the assage, 'but' 'being capableito'givejwa i: 1 1 yiel ingly, if a*ball=1s1forcedthroughthe passage under some pressure, whereafter the lips will return into the original positions owing to their roper el asticltyd Ii -order to prevent the described ieldingv'a of the lips 'a after the insertion of all balls, a wedge e or the like. of any convenient ma terial may be forced into the 'incisure' b and bent to embrace the outer ring g, as illus trated in Fig. 2. This wedge has notbeenftp sentation of thefincisure b. On 'thei'nner ring it a like wedge may be used,}however a short wedge 0," such as shown in Fig. ;3," will also serve in -many cases. 1

, In mar i wedges, any other means 'producingthe'sa'me efiect can be applied, for instance, a setscrew f may-press upon the lip a, as illustrated-in Fig. 3 in connection with the outer In lieu of tapering or overhanging hpsa, gh ps may :be provided, whlch- 'nor mally present the aperture of the passage the same size at"- all points. ;Th'erefore" ;.th balls can easil be: inserted, Whereup'onjpartialclosing '0 the passage will be possibleand obtained by causingthe elastic lips to approach under pressure with the aidof tli above-described wedges or' other means fo the structure of the material around thepasof 'th tion of aball sllppe into the bearing; I This result will be obtained, for example, by tem pering the adjacent part-1 0 f the hardendd same advantageous effect on one ring only, if the insertion of the balls is performed in the relative eccentric position of the rmgs in the well known manner, or in ball bearings having two rows of balls and a corresponding number of race ways, the yielding lips being made on elther side of the race rings for providing a separate lpassage lead ing to the several ball races. I ustration of these modifications has been omitted, as any one skilled in the art will be able to .make them, and because they have no essential reference to the subject matter of the invention relating more specially to the passage itself. v

It will be seen that the main principle of the invention is the establishment of means for inserting the balls throu h the annular 'interstice between the rings y provldlng a filling lace where the lateral shoulder of one or 0th rings is, by means of incisures in the metal or in some other suitable way,

made so resilient or elastic as to yield to rovide a passage for introducing the balls. 11 the case of incisions producing semi-detached lips, a broader rinciple is involved viz: the production 0 a passage which whether it be normally contracted or of suitable size to admit the balls without yielding, can. afterward be contracted or partially closed by means of the lips, as explained in the foregoing specification.
